# Showering cost calculator

Answers the question: How much does it cost to take a shower?

Use this calculator to find the cost of taking a shower. The calculator considers electricity prices, water costs, the number of showers per day, and the number of people in the household. Please note that the shower's water flow rate significantly affects the total shower cost. Experiment with this to see the effect on the shower cost.

For this calculation, we assumed a shower temperature of 35 degrees and that an electric hot water tank heats the water. The water-saving shower head will set the flow rate to 8 liters per minute, the standard flow rate is 13 liters per minute, and the high flow rate is 18 liters per minute.

### Cost per shower was calculated like this:

Step 1

First we need to calculate the variable cpm. cpm = cost per minute.

Step 2

Then we need to calculate the variable w. w = electricity cost per minute.

Step 3

Then we need to calculate the variable wp. wp = water price.

Step 4

Finally we put it together and calculate it like this:

### Cost per day was calculated like this:

### Cost per month was calculated like this:

### Variables used in this formula

l = Average shower length in minutes

p = Electricity cost per kWh

wa = Water cost per cubic meter

s = Number of showers per day

o = Number of persons in the household

Depending on your choice when selecting water flow rate a constant is applied as the variable fl in the formula.

Water flow rate | fl |
---|

Water-saving shower head | 8 |

Standard | 13 |

High water usage | 18 |
